Modafinil 200mgis a drug that promotes wakefulness and is prescribed for the treatment of excessive sleepiness in narcolepsy, obstructive sleep apnea, and shift work sleep disorder. It can be used in obstructive sleep apnea to alleviate chronic sleepiness; however, it does not treat the airway blockage. Sufficient sleep and the proper treatment of the disease are critical.



Modafinil works through mechanisms that relate to neurochemical pathways in the brain that regulate wakefulness; its exact mechanism of action is not yet known. Some side effects include headache, nausea, dizziness, and insomnia. The recommended dose and timing may vary depending on the diagnosed disease. People are advised to strictly follow their doctor's recommendations concerning the drug intake without changing doses on their own initiative. Modafinil interacts with many other medications, including hormonal contraceptives. Those who use this medicine should consult a medical practitioner about their diseases, drugs, and other risks before taking it.
